Python Program to Convert Two Lists Into a Dictionary – 2025

Hey guys, in this blog we will see a Python Program to Convert Two Lists Into a Dictionary.

Example 1: Using zip and dict methods

index = [1, 2, 3]
domains = ['ml', 'dl', 'ai']

dictionary = dict(zip(index, domains))
print(dictionary)

Output

{1: 'ml', 2: 'dl', 3: 'ai'}

• zip takes 2 lists and merges them element-wise.
• zip(index,domain) will make a list like [(1,’ml’),(2,’dl’),(3,’ai’)].
• And then dict() method will create a dictionary from it.

Example 2: Using list comprehension

index = [1, 2, 3]
domains = ['ml', 'dl', 'ai']

dictionary = {k: v for k, v in zip(index, domains)}
print(dictionary)

Output

{1: 'ml', 2: 'dl', 3: 'ai'}

• This is also similar to the first one.
• But here we are not using dict(), instead, we are traversing in the zipped list and explicitly assigning key:value pairs.
